WATER-GAG E.

SPECIFICATION forming part of Letters Patent No. 538,7 seaweed May 7, 1 895.

Application iiled May 26, l 894.

.To all whom it may concern:

Be it known that I, MINOTT W. SEWALL, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful p Improvements in Water-Gages for Steam-Generators, of which the following is a specification.

This invention relates to means for conveniently connecting a waterglass and a seto ries of gage-cocks to a steam-generating apparatus in such manner that communication with the glass can be shut off when it needs repair, or is to beremovedfor any reason, and the cocks be left in full connection for '15 duty; or the cocks be shut off and the glass loe left in connection.

To this end, the invention consists in a double or two-chambered water-column,which is adapted to receive the water-glass and the zo gage-cocks, is arranged to be connected with the generator, and is providedv with suitable valves to govern the inlet of steam and water to the respective chambers.

It-also consists in so constructing the column that two valves, one at the top and the other at the bottom will open bothchambers in the column, and will shut off either, at will; and further consists in certain features of construction and arrangement, all as herego inafter described and claimed.

In the accompanying drawings, Figure l represents a front view of the preferred form of column, with the water-glass and gagecocks in place thereon. Fig. 2 shows a side view'ot the same, with pipe VVconnections tok the generator. Fig. 3 represents, on a larger scale, ahorizontal section of the, same on line X X, it being understood that asimilar section on the line Y Y will show the same 4o construction.

A A denote the preferred form of double or twin water-column, which has two verticall compartments or chambers, B, C.' For convenience, and tofreduce expense, the column 4 5 is preferably cast or formed inv one piece. It

, is, also, preferably of the same design and construction both at the top and bottom, in order that it may be applied either end up, so that the gage-cocks and valve-wheels may be upon 5o the right or the left hand of the column after it is in place, as may be the most desirable.

From one -of the vertical chambers, as B,

column, so as to communicate with the chamber, C, which vis separated from the chamber, B, by apartition, b, extending the full length of the column. p

Upon its rear face, the column is provided with bosses or projections, G, G', which are made hollow to form valvechambers, g, from each ofV which, outlet-ducts, H, I, lead into the chambers, B, C, respectively. On their rearfaces, the bosses have inlets, c, to receive horizontal pipesfJ, J, for connecting the column with the steam-generator, and the bosses preferably have inlets, c', at the top and bottom, also, so as to receive vertical, generator-connections,j, j', (shown by dotted lines in Fig. 2,) thereby enabling horizontal or vertical connections to be made-it being understood ,that the vertical inlets are to be plugged if the horizontal ones be used, and vice versa. Y

In each of the chambers, g, a valve, K, is located, the spindle, lo, of which is threaded through a plug, 7a', and is provided on its outer end with a'wheel L. Around the Wheels L, hanging chains are intended to pass,in order that the wheels may be conveniently turned when in an elevated position, and the perimeters of the wheels are preferably provided with spiral ribs, Z, between the convolutions of which the chains are wound, the ribs separating the coils of the chains. The chains may be connected at their lower ends so that a single pull will turn both of the wheels, L, and thereby operate both valves, K, simultaneously.

VI, and are in axial alignment with the valve, K.

The normal position of each valve, K, is

midway between its seats, M, N, so that steam and waterenter both chambers, B, C, and thereby showin the water-glass and at the gagecocks. When, however, it is desired to remove or to shut olif the water-glass for any purpose, a closing of the valves on their seats, M,M,\villeffecttheobject,andleave the chamber, C, in full connection with the inlets from the generator; or if it be desired to shut off the gage-cocks, a closing of the valves on their seats, N, N, will produce the desired result, and leave the chamber, B, in connection with said inlets, so that at no time can the generator be without the protection of either the glass or the coc-ks.

The column is preferably provided with holes, 7i, 7i, and t', t', which are in alignment respectively with the several outlets, H, H, and I, I, from the valve-chambers into the chambers, 13,0, so that said outlets can be cleaned by an instrument inserted through said holes, which are normally stopped by plugs, d, as shown in Fig. 3. Each valve-chamber, g, is also preferably stopped at one end by a plug, m, the removal of which affords access to the chamber.

If desired, two water-glasses and two sets of gage-cocks may be used, a glass and a set of cocks being in communication with the chambers, B, C, respectively. It is obvious, also, that each of the valve-chambers may be supplied with a second valve, to close upon the seat, M, and open toward the valve, K, though such an arrangement would not be so desirable as that illustrated, as there might then be danger that both valves would be accidentally closed at the same time, and both glasses and cocks be thereby shut off.

From the foregoing it will be understood that, when the valve, K, is midway between the seats, M, N, water and steam will enter both chambers, B, C; that, when the valve is closed on its seat, N, as shown in Fig. 3, entrance to the chamber, C, will be closed and the gagecocks thereby be shut ott, out the chamber, B, will be in full communication with the generator; and that, when the valve is closed upon its seat, M, entrance to the chamber, B, will be closed and the water-glass be thereby shut 0E, but the gage-cocks will bein communication with the generator. At no time, therefore, can both the water-glass and gage-cocks be shut off at the same time, which insures au indication at all times of the height of the water in the generator.

What I claim as my invention, and desire to secure by Letters Patent, is-
